To @ZZ whom t may concern:

Be it known that I, JOSEPH R. HEBERT, a citizen of the United States, residing in the city of Brooklyn, Kings county, and State of New York, have invented certain new and useful Improvements in Tuck-Marking Attachments for Sewing-Machines, of which the following is a specification.

My invention relates to tuck-1narkng attachments for sewing-machines of the class provided with notch and point, gages, and graduated scales; and it consists in the construction and arrangement of the several parts forming the attachment, whereby the several operative parts may be adjusted as a whole in their relation to the needle-bar, and also each have a separate and independent adjustment in their relation to each other.

It also consists in the means for adjustably holding the operating-lever out of operative position for engagement with the needle-bar and in other details of construction, as will hereinafter be set forth in detail, and pointed out in the claims.

Referring to the drawings, Figure l represents a top view of my improved tuck-marker. Fig. 2 represents an end sectional'view cut through on the line fr ac, Fig. l, and Fig. 3 represents a side view showing the base-plate and slide in section cut through at y y, Fig. l. Figs. It, 5, 6, 7, S, and 9 represent detached parts.

In the drawings, A represents an attachingplate adapted to be held within a groove, with which the cloth-plate of the sewing-machine is usually provided, within which `a removable covering-slide is usually held, which serves as a cover over part of the shuttleraceway.

B represents a plate located above and sup ported by a vertically-pivoted connectingplate D, pivoted to the attaching-plate A. A detached plan view of the plate B is very clearly represented in Fig. 5 of the drawings. This plate B is provided with a projection or an upturned flange, which I term an ear, (more clearly shown in Figs. l and 3 of the drawings,) and to which one end of a lever or arm is secured, the opposite end of which is provided with a grooved circular device adjustably attached, the adj ustability being for the purpose of changingi the position of the circular groove in its relation to the engagingsurface, with which it contacts in operating when undue wear appears. In the present instance a single screw (shown at a) serves as the means'for adjusting the parts, although other means might be employed to hold the parts in a desired position, as it is the adjustability of the parts lin their relation to 6o each other in the combination described that I claim (among other things) as new. The plate B also has a lexible spring attached thereto, (see Fig. 5,) with its surface toward the supporting part slightlyrounded. Thisdevice serves as a sort of presser and smoother for the fabric passing beneath.

A top view of the device is very clearly represented in Figs. l and 5 of the drawings, while edge views may be seen in Fig. 3.

Intel-posed between the plates B and D already described is another one, (represented at 0,) a detached View of which is shown in Fig. 6 of the drawings. This plate is provided With a vertical and an overhanging pro- 7 5 jection, these two parts .serving as a guide for the edge of the material while being fed along, and also to confine between them the slideplate B, which carries the marker, the overhanging part of one of the guides referred to 8o serving to keep the strips from riding over the tops of the vertical parts when the attachment is in operation. A third vertical projection or flange, formed by upturning a portion of the said plate C, is located at or 85 near the rear end of the said plate, which serves as a means for moving the guide by the hand to and from the marking-points,

thereby defining the distance of the mark from the tuck which is being operated upon. 9o The plate C, together with all of the parts above A and D, is held in position by the thumb-screw g.

The drawings at D represent another plate (more clearly shown in Fig. 7) as detached 95 from its connecting parts, forming a kind of pivoted chair, upon which the other principal operating devices are supported upon the main plate A, previously referred to. This plate D is pivotally attached to the main plate roo A by screw or rivet, thus allowingit, with its connecting parts, to be swung in a horizontal plane in and out of position at right angles or parallel, as shown by dotted lines in Fig. 1 of the drawings, for a greater convenience of boxing and condensing'the same when not in use. An end view of this plate or chairD is represented in Fig. 8, showing the pivotpin at D', and a loop-guide h, which serves to support a spring-presser similar to the one carried by the plate B, before described, while g represents a screw for a thumb-nut which secures the several parts together. The sliding plates and gages are confined by a sort of covering-plate. (Shown at E in the drawings.) A detachedenlarged view thereof is shown in Fig. 9 of the drawings. This plate is provided with an opening for the passage of the fastening-screw and a slit serving to intersect with the loop 71., before referred to, to assist in maintaining it in the proper position. The actuating-leveris also attached to this plate, together with a catch-sprin g for holding the said actuating-lever upright, or nearly so, when not required to be used.

By the construction and combination of parts described I am enabled to produce an attachment that is not only adjustable in all desirable Ways for effective operatiombut all parts except plates A and D are detachably held by a single screw alone. ating-lever for operating the marking-arm is represented in Fig. 4t as detached from its connecting parts and in Fig. 2 connected and; in position to receive the contact of the needle-bar, by which it is moved. The dotted lines show the position of the lever when held in a vertical position when desirable for nonoperation. The notches on its periphery are entered by suitable spring. The grooved wheel is adjustably held upon the arm, which is vibrated by contact of the needle-bar upon the operating-lever and its position changed whenever it becomes worn from use. In this way the parts for marking vmay be kept in proper Working condition by the operator.

The operation of the attachmentis so similar to those in general use that a detailed explanation would seem superfluous.

Having thus set forth my invention, what I claim as new, and desire to secure by Let-ters Patent of the United States, is-

1. The combination, in a tuck-marker, of the main supporting and holding plate, the plate D, vertically7 pivoted thereon to horizontally rotate, two independently-adjustable plates sliding upon said vertically-pivoted plate and carrying the marking apparatus The actuand'gage, respectively, and means for adjustably holding said sliding plates and marking apparatus and gage carried thereby in their relations to each other upon said :rotatable vertically-pivoted plate, substantially as and for the purpose set forth.

2. In a tuck-marker, the combination, with a base-plate and a supporting-plate vertically pivoted thereon to be rotated in a horizontal plane, of an independent operating-gage, a slide provided with a creasing-blade, a marker, and a smoother, and means for adjustably holding said gage and slide upon the said .vertically-pivoted supporting-plato, substantially as and for the purpose set forth.

3. The combination,in a tuck-marker, with the plate A and a supporting-plate vertically pivoted thereon, of an adjustable sliding plate supported on said vertically-pivoted supporting-plate, carrying a grooved wheel and creasing-rib, substantially as and for the purpose set forth.

4. The combination, in a tuck-marker, of a main supporting-plate, the plate D, vertically pivoted thereon, two independently-adj ustable plates supported on said vertically-pivoted plate carryingthe gage and markingapparatus,respectively,andathumb-screwforholdsaid adjustable plates and marking apparatus and gage supported thereby adjustable in their relation to each other, substantially as described, and for the purpose set forth.

' 5. The conibination, in a tuck-marker, of a base-plate, a supporting-plate vertically pivoted on said base-plate, a sliding gage .and a sliding plate carrying the marking apparatus supported on said vertically-pivoted supporting-plate, and a covering-plate and screw to engage with and hold said sliding gage and the sliding plate carrying the marking apparatus adjustable in their relation to each other, substantially as and for the purpose set forth.

6. The combination, in a tuck-marker, of a supporting-plate, the marking apparatus and gage supported thereon, means for holding said marking apparatus and gage on the said supporting-plate, an actuating-lever provided with notches, and a spring for engaging said notches to hold the lever out of operative position, substantially as and for the purpose set forth.
